Just waves length, not waves amplitude - perhaps a small introduction of a set of different
amplitude could be good too.
I think that HTC has experimented a bit before to choose waves length and amplitude but after many weeks ideas could change.

p.s.
My pc's performance is poor (as Skuzzy said

) so i don't want to see any dramatically changes in AH requirements as many of you.
I think that waves length is just a simple value parameter in AH and perhaps a more long wave length could have a positive impact on frame rete.
